Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00029 | $0.00353 |
| Opus 5 | $0.00015 | $0.00177 |
| Sonnet 5 | $0.00006 | $0.00071 |
| Haiku 4.5 | $0.00003 | $0.00035 |
Grade A, and why
include-test-files-that-assert-on-behavior-being-changed-in-decl scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
include test files that assert on behavior being changed in declared scope
Trigger
- (no explicit trigger metadata; cluster derived from category/tags)
Required Procedure
- include test files that assert on behavior being changed in declared scope
- review test assertions before delegating bug fixes

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

include-test-files-that-assert-on-behavior-being-changed-in-decl is a skill published in the GitHub repository ZaxbyHub/opencode-swarm (466 stars, last pushed yesterday), licensed MIT. It adds 29 tokens to every session and 353 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
Other skills, from other repositories
armada-ledger
Pick the right ledger for a finding. Use when writing defects, adversarial findings, or security findings. Triggers on: ledger, defect, adversarial, security finding, DEF-001, ADV-001, SEC-001.
armada-tdd
Test-driven development for armada workers. Use before writing any implementation. Triggers on: TDD, failing test, test first, write a test.
armada-verification
Mandatory pre-completion verification and evidence checklist before reporting done.
armada-pr
PR-first finish for a feature lane. Use before reporting a feature done. Triggers on: PR, finish feature, gh pr create, merge, lane complete.
utils-unification
Prioritize extracting, standardizing, and consolidating utilities so shared logic is consistent, discoverable, and testable. The goal is to prevent duplication and drift while keeping utilities sharply scoped and aligned to screaming architecture.
polish
Prioritize overall quality, coherence, and finish across the scenario. Do not break functionality or regress tests; all changes must maintain or improve completeness. Avoid large structural refactors or new feature work — focus on refinement, not reinvention.
